We consider the two dimensional version of a drainage network model introduced by Gangopadhyay, Roy and Sarkar, and show that the appropriately rescaled family of its paths converges in distribution to the Brownian web. We do so by verifying the convergence criteria proposed by Fontes, Isopi, Newman and Ravishankar.

Introduction The vertical and horizontal movements of the Earth crust have caused extensive changes in surface phenomena, in the active tectonic regions. In order to measure some of these changes, morphometry analyses have been used to evaluation of the amount of tectonic activity. These analyses are useful tools for analyzing existing feature at the ground level and provide a proper understan...

Purpose: The objective of this work was to evaluate methods charging urban drainage fees in order finance and guarantee the maintenance operation a network residential subdivision located city Rio de Janeiro.
 
 Theoretical framework: intense growth associated with process soil sealing areas has caused, over years, increase occurrence intensity disasters related floods, reduce capacit...

Due to the existence of drainage networks, urban areas have formed their own hydrological mechanism. The pretreatment complex and elaborate network data has become a challenging step in building an model. This study proposes network-combing method based on potential outfall mechanism for system, analyzes topological structure underground network, generates subcatchment (SBPO). Two methods are c...
